General correlation between the chemical shift of hyperpolarized ~(129)Xenon and pore size of mesoporous solids

摘要

We report the variation of ~(129)Xe chemical shift d versus the pore size,the temperature and the xenon pressure of xenon adsorbed on mesoporous materials prepared in different synthesis conditions.The use of hyperpolarized xenon allows us to measure spectra at very low concentration of xenon,where 5 reflects mainly interaction between the adsorbed xenon atoms and the surface.We deduce the heat adsorption of xenon adsorbed on the surface of studied materials.To cite this article:E.Haddad et al,C.R.Chimie 7(2004).
